基于知识的信号交叉口配时设计系统

A KNOWLEDGE_BASED SYSTEM FOR THE DESIGN OF SIGNALIZED INTERSECTIONS

信号配时是影响信号交叉口通行能力的关键． 本文根据专家系统的有关理论和信号交叉口的配时设计原理， 研究了一种基于知识的信号交叉口配时设计系统， 并编写了相应的软件． 研究该系统的主要出发点是基于交通流的随机性和不确定性较强， 难以用精确的数学模型加以描述， 但是可以根据经验进行适当的分析． 经过计算比较， 本系统要优于目前的交叉口信号配时方法．

Design of signalized intersections, which can directly affect the performance of urban transportation, needs to know the traffic flow regulation and how the signal systems operate. This paper proposes a knowledge_based system for the design of signalized intersections based on Expert Systems and the timing of signalized intersections. The results show that the system algorithms are superior to the existiny method at present.
